Abstract

1298101 Gettering cathode-ray tubes GENERAL ELECTRIC CO 17 March 1970 [24 March 1969] 12751/70 Heading H1D In a getter assembly as described in Specification 1,274,289 comprising a getter container 25 adapted to be cantilevered from an electron gun 14 by a thermally conductive support strip 27 so as to extend into the funnel portion 12 of the envelope 10 of a cathode-ray tube, the strip 27 is provided with reinforcing means 30 adjacent the container 25 to resist deformation of the strip by heating when the getter is flashed. Preferably one or more ribs 30 are formed integrally with the strip or are attached thereto. The hot container 25 and/or strip 27 are thus prevented from contacting and causing heat cracks in the glass envelope 10.
